SPRING BALANCER – PLEASE INSPECT THE FOLLOWING:
Note: All spring systems are designed to assist in the operation of opening and closing the
door. The door should never free fall or fly open buy itself. All spring systems are designed
for both cables to have uniform pull so the door doesn’t pull to one side or the other.
1. Does the door “balance” (neither rise nor fall) without assistance?
2. Are the cables (door in open position) nearly vertical from the cable anchor bracket
to the cable drum? The cables should NOT skip grooves or travel over another cable
on the drum.
3.
Inspect Roll-up Door Cables for fraying or wear damage and replace if needed. (See Figure 4).
4. Inspect Cotter Pins and Cable Anchor Bracket Pins for wear damage and replace if needed.
(See Figure 4).
SINGLE SPRING – PLEASE INSPECT THE FOLLWING:
1. Are the cable drums tight against the counterbalance shaft bearings, the set screws
properly tightened, and both cables are tight and have equal tension?
(See Figure 5).
